Given numbers are 687,535,474,105,100
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 687,535,474,105,100 is 4065047700.
Find LCM of 687,535,474,105,100 with Prime Factorization
| 2 | 687, 535, 474, 105, 100 |
| 3 | 687, 535, 237, 105, 50 |
| 5 | 229, 535, 79, 35, 50 |
| 229, 107, 79, 7, 10 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 229 x 107 x 79 x 7 x 10 = 4065047700
Therefore, the lowest common multiple of 687,535,474,105,100 is 4065047700.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
687 x 535 x 474 x 105 x 100 = 1829271465000
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
687 : 1, 3, 229, 687
535 : 1, 5, 107, 535
474 : 1, 2, 3, 6, 79, 158, 237, 474
105 : 1, 3, 5, 7, 15, 21, 35, 105
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 687,535,474,105,100, is 1.
Now, the common factors can be found like this.
687:3x 229
535:5x 107
474:2x 3x 79
105:3x 5x 7
100:2x 2x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 5 = 450
Therefore, the value for common factors is 450.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 1829271465000/(1x450)
LCM = 1829271465000/450
LCM = 4065047700
Thus, we can understand that the LCM of 687,535,474,105,100 is 4065047700.
